It looks like V1 is set to switch every 3 seconds, but the output only shows 9 milliseconds.

Thank you dear godfreyl
it works fine.Is it possible we have a continuous wave source generator with VPWL?

I don't know your software. Doesn't the VPWL repeat indefinately? Then all you have to do is increase the simulation time.

I think the VPWL source does not repeat and remains at the final voltage value after the last PWL time-voltage value in the list.
